Why does ObjectOutputStream.writeObject(Object o) not take a Serializable? Why is it taking an Object?
This is because
writeObjectinObjectOutputStreamoverrides the method in theObjectOutputinterface which does not require that the object beSerializable.The
ObjectOutputinterface specifies methods that allow objects to be written to a stream or underlying storage, but this may be achieved by a process other than serialization. TheObjectOutputStreamimplements this functionality, but requires serializable objects. However, it cannot modify the signature of the interface that it implements.
